About CNTXT
- CNTXT is building voice AI infrastructure for the Arabic speaking world. We work on the hard problems — natural speech synthesis, real time transcription, and conversational voice systems — with a focus on Arabic language quality that actually serves the region's speakers.
The Role
- We're looking for an AI engineer or researcher who is passionate about voice and speech technology. You'll work directly on the models and systems that power our speech products — evaluating architectures, running fine tuning experiments, and shipping improvements to production. This is a hands on r
What You'll Work On
- Benchmark and evaluate TTS and ASR models on Arabic test sets — measuring WER, speaker similarity (SIM), naturalness, and dialect coverage across MSA and regional varieties
- Fine tune pretrained TTS models on curated Arabic data — including ablations on diacritized vs. undiacritized input, dialect specific training splits, and voice prompt conditioning
- Experiment with audio tokenizer and codec configurations — comparing discrete RVQ representations against continuous latent approaches and their effect on Arabic phoneme accuracy
- Build and maintain Arabic speech data pipelines — audio sourcing, normalization, diacritization, quality filtering, and manifest generation for model training
- Optimize models for production serving — streaming chunk generation, KV cache tuning, quantization, and batched inference for low latency Arabic TTS and ASR
- Evaluate and adapt speech to speech pipelines — integrating ASR, LLM, and TTS components with attention to end to end latency and Arabic conversational quality
What We're Looking For
- Strong foundations in machine learning and deep learning
- Hands on experience training or fine tuning neural models — domain matters less than depth
- Comfortable with Python, PyTorch, and the HuggingFace ecosystem
- Able to read research papers and translate ideas into experiments independently
- Clear communicator who can work across research and engineering
Nice to Have
- Native or fluent Arabic speaker — a real advantage when evaluating synthesis naturalness and dialect quality
- Prior work with speech or audio models (ASR, TTS, speaker verification, codec, VAD, enhancement, or similar)
- Familiarity with Arabic linguistic structure, diacritization tools, and NLP preprocessing for Arabic
- Experience with inference optimization — quantization, speculative decoding, CUDA kernels, or serving frameworks (vLLM, TensorRT)
- Publications or open source contributions in speech or audio
What We Offer
- Work at the frontier of Arabic voice AI — a genuinely underserved, high impact area
- Direct influence on product and research direction
- Small, focused team — your work ships and matters
- Competitive compensation and remote flexibility
